Cryo your cables?

I was talking with a buddy of mine that builds racing engines for karts and the subject of cryogenic freezing came up. For the past couple of years this has been THE hot thing to have done to your engine parts to reduce wear and friction. I checked out a place on the web called 300below.com that does this work. Now for the interseting part relating to cables. They say that one of the frequently treated alloys is copper, espescially welding electrodes. Quote- "The increased durability of Copper from cryogenic treatments is increased homogeneity of the crystal structure. The material becomes more compact, dissolving gaps and discolorations or, for example, chrome carbides found in class II copper. Because of structural compactness there is less electron obstruction which improves electrical conductivity. It has also been learned that as a result of increased conductivity, welding amperage can be reduced thereby further prolonging the service life of electrodes." This got me thinking, what would such a difference in crystal structure do to interconnects and speaker cables? It would seem that what they claim of reduced electron obstruction and increased conductivity would be a positive thing in an audio environment. Has anyone ever thought about this before or actually had their cables treated? I would like some other opinions on this. I'm definitely having my drag-bike engine shipped out this winter to be treated, but I never thought before about how it might make cables sound different.

Yes, Cryo definately works! I discovered this process in the last year, and have been shocked at how much difference a deep freeze can make. Apparently, this is no snake oil, but a proven way to enhance the micro crystaline structure of any metal alloy. A aerospace buddy informed me about the structural benefits with the cryo process, and I wondered if these enhancements might improve the performance of my cables. Sonically, they become more "laid back" sounding, and have a slightly more open soundstage. Now, for the kicker: You don't have to spend a ton of money at a cryo place in order to cryofreeze your cables. All you have to do is buy a block of dry ice, put it in a styrofoam container, place your cables in the container, seal the container, and put it in your freezer overnight. The sonic improvements are similiar to the expensive deep freeze cryo places, except it only costs you 10 bucks in dry ice!

Answer to question, What does dry ice do? In a nutshell, it has the same sonic benefits as the cryo deep freeze process. Some history: In the past one of my buddies and his audiophile friends would rent out a deep freeze cryo container in which they could cryo all of their equipment and wires at the same time, to save on the cost (If I recall it was $800 per cryo session). Everyone throughout the country would have to ship it to one of the audiophiles in the Chicago area (where the cryo service was). This saved everyone money, but overall, it was a logistical nightmare for everyone involved. One guy started to wonder if the same sonic benefits could be obtained from a lesser "deep freeze", invoving the use of something like dry ice. He made a styrofoam contatiner in which he could put dry ice and cables, sealed it, and put it in his freezer over night. After this process was done, he compared the sound of the dry iced cables, to his cables that had been cryo treated (Note: The cryo and dry iced cables were the same exact design) It turned out to be better than he had hoped. Both cables were indistiguishable from one another! I am sure that the cryo treatment is the best way freeze alloys, but...when you compare costs (and more importantly, the identical sonic improvements) the dry ice choice is a no brainer. Who cares if this process does not last forever? For $15 bucks in dry ice, you can refreeze your entire system! If the true cryo process is temporary, you'll be out of some serious money.
